How to Fix Starfield Error 0xc000001d on your Windows PC

Encountering the error code 0xc000001d while launching Starfield on your Windows PC can be frustrating. This issue prevents the game from starting, whether you’ve purchased it directly or accessed it via Xbox Game Pass. Fortunately, there are several solutions you can try to resolve this problem and get back to exploring Bethesda’s latest RPG adventure.

Enable AVX Extensions

The error may occur if Advanced Vector Extensions (AVX) are disabled on your CPU. Enabling AVX can enhance performance for applications that use vectorized algorithms, such as Starfield. If your processor supports AVX, you can enable it through the Command Prompt or your system’s BIOS settings.

Open Command Prompt as an administrator. Click the Start menu, type cmd, right-click on “Command Prompt,” and select “Run as administrator.”

In the Command Prompt window, type the following command and press Enter:

bcdedit /set xsavedisable 0

Restart your computer to apply the changes.

If the issue persists, you might need to enable AVX extensions in your BIOS or UEFI settings.

Restart your computer and enter the BIOS or UEFI setup menu. This is usually done by pressing a key like F2, F10, or Delete during startup.

Navigate to the ‘Advanced Settings’ or ‘Overclocking’ section.

Locate the option for AVX extensions, often labeled as ‘AVX’, ‘AVX Instructions’, or ‘Advanced Vector Extensions’, and enable it.

Save your changes and exit the BIOS setup. Your computer will restart automatically.

Once AVX is enabled, try launching Starfield to see if the error has been resolved.

Reset Game Save Data

Resetting the game’s save and configuration data has helped many users fix the 0xc000001d error. This process involves deleting specific files, which the game will regenerate upon launch.

Open File Explorer and navigate to:

%LOCALAPPDATA%\Packages\BethesdaSoftworks.ProjectGold_3275kfvn8vcwc\SystemAppData\wgs\

Delete all files and folders inside the wgs directory.

Go to the game’s installation folder. For Xbox Game Pass users, this is typically:

C:\XboxGames\Starfield\Content

Within the Content folder, delete everything except the DATA folder. Do not delete the DATA folder, as it contains essential game files.

Ensure the ‘Starfield.exe’ file is deleted from the installation directory.

Open the Xbox app and navigate to the Starfield game page.

Click the three dots next to the ‘Play’ button and select ‘Manage’.

Switch to the ‘Files’ tab and click ‘VERIFY AND REPAIR’. This will scan for missing or corrupted files and repair them.

After the process completes, launch Starfield to check if the error persists.

Update Graphics Card Drivers

Outdated or incompatible graphics drivers can cause game crashes and errors. Updating your GPU drivers ensures optimal performance and compatibility with new games like Starfield.

Right-click the Start menu and select ‘Device Manager’.

Expand the ‘Display adapters’ section to see your graphics card.

Right-click your graphics card and select ‘Update driver’.

Choose ‘Search automatically for drivers’ to let Windows find and install the latest driver.

If an update is found, install it and restart your computer.

If Windows doesn’t find an update, download the latest driver directly from your graphics card manufacturer’s website:

Delete GPU Cache

Corrupted GPU cache files can sometimes cause errors when launching games. Deleting these cache files allows your system to regenerate them, potentially resolving the issue.

Press Windows + R to open the Run dialog.

Type or paste the appropriate path based on your GPU manufacturer and press Enter:

For AMD GPUs: %LOCALAPPDATA%\AMD\DxCache
For NVIDIA GPUs: %LOCALAPPDATA%\NVIDIA\DxCache

Delete all files inside the DxCache folder.

Open the Run dialog again, type %LOCALAPPDATA%\Starfield\, and press Enter.

Delete the pipeline.cache file in the Starfield folder.

Restart your computer and launch Starfield to see if the error has been fixed.

Close Background Apps

Running multiple programs simultaneously can strain system resources, leading to crashes or errors. Closing unnecessary background applications frees up CPU, memory, and disk resources.

Press Ctrl + Shift + Esc to open Task Manager.

In the ‘Processes’ tab, identify programs consuming significant resources.

Right-click unnecessary programs and select ‘End task’ to close them.

Close web browsers, media players, or other games not in use.
Disable real-time scanning in antivirus software while playing.
Restart your computer before launching the game to clear temporary processes.

Run the Game as an Administrator

Running Starfield with administrative privileges can prevent permission-related issues that may cause the game to crash.

Navigate to the game’s installation folder and find ‘Starfield.exe’.

Right-click ‘Starfield.exe’ and select ‘Run as administrator’.

If this resolves the issue, you can set the game to always run as administrator:

Right-click ‘Starfield.exe’ and choose ‘Properties’.

Go to the ‘Compatibility’ tab and check ‘Run this program as an administrator’. Click ‘OK’ to save changes.

Restart Your PC

A simple restart can often resolve temporary glitches or conflicts causing the error.

Save all work and close open applications.

Click the Start menu, select ‘Power’, and choose ‘Restart’.

After rebooting, try launching Starfield again.

Keep the Game Updated

Developers release updates to fix known bugs and improve performance. Ensuring Starfield is up to date can resolve the 0xc000001d error.

Open the Xbox app or Steam, depending on where you purchased the game.

Navigate to your game library and check for updates for Starfield.

If an update is available, download and install it.

Turn Off GPU Overclocking

Overclocking can enhance performance but may also cause instability in some games. Disabling GPU overclocking can help stabilize Starfield.

Open your overclocking software (e.g., MSI Afterburner).

Reset GPU settings to default values.

Save changes and close the software.

Reinstall the Game

If the error persists, reinstalling Starfield can replace corrupted or missing files.

Uninstall Starfield via the Xbox app or Steam.

Delete any remaining game files from the installation directory.

Restart your computer.

Reinstall Starfield from your game platform.

If you’re having trouble installing from the Xbox app, consider installing the game from Steam instead.
